Subject: [PATCH] Xi/randr: fix handling of PropModeAppend/Prepend
|
|
|
|
The handling of appending/prepending properties was incorrect, with at
|
|
least two bugs: the property length was set to the length of the new
|
|
part only, i.e. appending or prepending N elements to a property with P
|
|
existing elements always resulted in the property having N elements
|
|
instead of N + P.
|
|
|
|
Second, when pre-pending a value to a property, the offset for the old
|
|
values was incorrect, leaving the new property with potentially
|
|
uninitalized values and/or resulting in OOB memory writes.
|
|
For example, prepending a 3 element value to a 5 element property would
|
|
result in this 8 value array:
|
|
[N, N, N, ?, ?, P, P, P ] P, P
|
|
^OOB write
|
|
|
|
The XI2 code is a copy/paste of the RandR code, so the bug exists in
|
|
both.
